• Mutually injection locked gain switched optical frequency combs for dual comb spectroscopy of H2S 

  Martin, Eamonn P.; Chandran, Satheesh; Rosado, Alejandro; Soderholm, Erik P.; Alexander, Justin K.; Peters, Frank H.; Ruth, Albert A.; Anandarajah, Prince M. (Optical Society of America, 2020-05)

  Application of two mutually injection-locked gain-switched optical frequency combs for near-infrared spectroscopy of H2S in air is demonstrated. The high phase correlation between OFCs allows measurement sensitivities of ...
• Multi-scale theory and simulation of direct-gap group-IV semiconductor alloys 

  Broderick, Christopher A.; O'Halloran, Edmond J.; Dunne, Michael D.; Kirwan, Amy C.; Andreev, Aleksey D.; Schulz, Stefan; O'Reilly, Eoin P. (Institute of Electrical and Electronics Engineers (IEEE), 2020-07-13)

  Alloying of Ge with other group-IV elements - C, Sn or Pb - represents a promising route to realise direct-gap group-IV semiconductors for applications in Si-compatible devices, including light-emitting diodes and lasers, ...
• A 915 MHz wristwatch-integrated antenna for wireless health monitoring 

  Kumar, Sanjeev; Buckley, John L.; Barton, John; Newberry, Robert; Dunlop, Gary; Rodencal, Matthew; Webster, Carlo; Pigeon, Melusine; Scanlon, William G.; O'Flynn, Brendan (Institute of Electrical and Electronics Engineers (IEEE), 2020-03)

  A compact 915 MHz antenna integrated within a wristwatch wireless sensor device is presented. The antenna is a variant of a planar inverted-F antenna (PIFA) and uses a dual-resonator configuration. The results of simulation ...
• Towards autonomous smart sensing systems 

  Haigh, Peter; Hayes, Michael; Gawade, Dinesh R.; O'Flynn, Brendan (Institute of Electrical and Electronics Engineers (IEEE), 2020-06-30)

  Since the 1990's, researchers in both academia and industry have been exploring ways to exploit the potential for Wireless Sensor Networks (WSNs) to revolutionize our understanding of -and interaction with -the world around ...
• A wearable hybrid IEEE 802.15.4-2011 ultra-wideband/inertial sensor platform for ambulatory tracking 

  Walsh, Michael; Tedesco, Salvatore; Ye, Tingcong; O'Flynn, Brendan (ICST (Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering), 2014-09-29)

  Ultra-Wideband (UWB) transceivers and low-cost micro electro mechanical systems (MEMS) based inertial sensors are proving a promising hybrid combination for location specific wearable applications. While several hybrid ...
